We also appear to be having this problem under .net 2.0 when we serialize an
object that contains a (large) hashtable:

(InvalidOperationException)
Hashtable insert failed. Load factor too high.
- at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean
add)
- at System.Collections.Hashtable.set_Item(Object key, Object value)

Any insight would be appreciated!

Thanks!
